I used a 1 lb bag of rice, 6 cups of water, 2 cups of chicken broth (optional as you could use water only), 1/2 cup diced carrots (again optional).
Throw it all into the slower cooker and cook 2 hours for white and 4 hours for brown rice.
Unfortunately I let mine cook a little bit too long. Oops! It is still good, just changed the texture a little.
May your day be filled with joy and contentment!
